Hi all,

I'm migrating from 4.3.3 to 5.3 and was wondering if there is more than
I need to consider besides booting from the CD-ROM and performing a
migration. Are there any directories I should consider important?

Thanks!

Best way to migrate: use alt_disk_install utility to clone one of your
rootvg drives (let's say hdisk0 as 4.3.3 source) to say, hdisk1.

That way you could boot off hdisk0 with 4.3.3 and boot off hdisk1 with
5.3, with a way to boot back into 4.3.3 if you don't like the 5.3
environment.

This is also a faster way of upgrading because you can do the cloning
while system is live without problems, then just reboot at a convenient
time to try 5.3. Downtime is only the time it's down while rebooting.

Doing this is as easy as making sure 4.3.3 is FULLY patched to the
LATEST stuff *then* break rootvg mirroring -- unmirrorvg rootvg hdisk1.

Then: alt_disk_install -C hdisk1

(-C = clone)

Come back in 45 minutes, done.

Reboot at convenience.

Read up on alt_disk_install stuff -- there's a few things to be aware
of, but it's pretty painless and works great for 4.3.3 -> 5.x migrations.

(You can also run this utility with SMIT, too.)

Put on the latest F80 firmware:
http://techsupport.services.ibm.com/server/mdownload

From the AIX 5.3 Release Notes (you should have a paper
copy with the AIX 5.3 CDs, or it is /usr/lpp/bos/README):

1.1.3 Some AIX Systems Might Not Boot From CD-ROM
Some AIX systems might not boot from CD-ROM because of firmware issues
To determine if your system will be affected by this problem, perform
the following steps before you migrate or install a running AIX 4.3, A
5.1, or AIX 5.2 system:
1. At the command prompt, type the following:
lscfg -vl cd*
2. Examine the data that is returned.
If Part Number is 04N2964 and ROS Level and ID is less than or equa
to 1_04 (for example, 1_02, 1_01, or 1_00), contact your local
service representative. Tell your service representative that your
system requires the CD-ROM firmware upgrade that is described in
RETAIN(R) TIP H1332.
If the data returned does not match the data described in the
preceding paragraph, your system is not affected by this problem.

1.4.7 xlC.rte Fileset
If you are migrating to AIX 5.3 from AIX 4.2.x or AIX 4.3.x, check the
level of the xlC.rte fileset by typing the following command:
lslpp -L xlC.rte
If the xlc.rte level is earlier than 5.0.2.x, you must apply APAR
IY17981 before migrating to AIX 5.3. Without APAR IY17981 installed, the
migrated system might fail to boot.
APAR IY17981 is available from the following Web site:
http://www.ibm.com/servers/eserver/s.../aixfixes.html

If you are migrating your system from AIX 4.3.3 to AIX 5L and you
installed the rpm.rte fileset without creating your own /opt or
/opt/freeware file system, after running the destroyRPMS command it is
recommended that you remove the /opt/freeware directory and the
/usr/opt/freeware directory before migrating. On AIX 5L, the system
provides a /opt file system into which the rpm.rte fileset is normally
installed. However, if the RPM Package Manager (RPM) finds a
pre-existing /usr/opt/freeware directory, it uses this location instead.
You do not need to do this if you want your RPM freeware installed under
the /usr file system, but the /opt file system is recommended.

1.4.15 System V Printing Subsystem
The System V Printing Subsystem is an alternate printing subsystem in
AIX. The installation of the bos.svprint.* filesets in a TCB environment
requires that the lp user ID (UID:11) and lp group ID (GID:11) are
present in the system. Otherwise, the installation of these filesets
will fail.
To avoid this problem, create the lp user (UID:11) and lp group (GID:11)
accounts on the AIX 4.3.3 system prior to the migration.


You should review the Release Notes to see if other
items may affect you.

just out of curiosity -- is anyone really using TCB in production
environment ?

Just a few people, since there is no point in using the TCB unless you're
going the whole way WRT security.

This includes logging, off-machine logging and archiving, auditing, audit
trail live analysis, no root password, function separation (i.e. the whole
shebang).

Justifiable for military or banking environments and little else.
